An environment's absolute humidity level
(or mixing ratio) can be measured and
expressed in units of grains per pound
(GPP) or g/kg. GPP is a more useful
moisture metric than RH to water damage
remediators. Using RH alone, a remediator
might unknowingly introduce moist air—
with a low RH but a high GPP—during a
job’s drying phase.
The sixth environmental parameter that the
EP8711P can measure is enthalpy. Enthalpy
is a measure of the amount of energy
needed to change the state of a substance
from a solid to a liquid or from a liquid to a
gas. The most common application for the
EP8711P's enthalpy-calculating algorithm is
measuring the enthalpy of vaporization of
air in an HVAC/R system duct.
The EP8711P is powered by (3) “AAA”
batteries (included).
